may be also one or more SERVICE_ON_RTE_SEG Service provided on route segment
An in-flight service like Air Traffic Control or Advisory Service is normally provided within an airspace or on an airway (which in this model is also considered an airspace) but it cannot be excluded that a service may be provided on a particular route segment.
must be provided by one and only one UNIT Organisation unit providing services
may be using one or more FREQUENCY Frequency
may be also one or more SERVICE_IN_AIRSPACE Service provided in airspace
This is the default situation for in-flight services (ACC, APP, SIGMET, etc.), these being provided within an airspace.
may be also one or more SERVICE_ON_STAR Service on STAR
Air traffic control, radar guidance (e.g.: Precision Approach Radar) or other services may be provided on an Instrument Approach Procedure, SID or STAR.
may be broadcast on one or more VOR VHF omnidirectional radio range beacon [VOR]
The type of service that is broadcast on a VOR frequency may be VOLMET or ATIS.
may be also one or more SERVICE_ON_SID Service provided on SID
Air traffic control, radar guidance (e.g.: Precision Approach Radar) or other services may be provided on an Instrument Approach Procedure, SID or STAR.
may be also one or more SERVICE_ON_IAP Service provided on IAP
Air traffic control, radar guidance (e.g.: Precision Approach Radar) or other services may be provided on an Instrument Approach Procedure, SID or STAR.
may be available according to one and only one TIMETABLE Timetable
may be also one or more SERVICE_ON_HOLDING_PROC Service provided on holding procedure
may be also one or more SERVICE_AT_AD_HP Service provided at an aerodrome/heliport
A service like APP, TWR, AFIS, MET, Pre-flight briefing etc. is provided at an aerodrome.
Note:
There is a difference between the place where the service is provided and the area covered by the information provided. E.g.: a Briefing service is provided at one aerodrome, but the area covered by the information in the briefing bulletin may include the aerodromes in several countries. This relationship is used to indicate only the first aspect, that is 'where' the information is provided.
